BACKGROUND ART

Visitors who view works of art in a place, such as an art gallery, a museum or the like, usually stand up for a long time at a single location in order to view works of art. Accordingly, a physical burden increases while viewing works of art. Furthermore, in ancient palaces, such as Gyeongbokgung Palace and Changgyeongung Palace, and expositions, movement for a long time is required, and thus a physical burden is imposed on visitors.

This physical burden may be further increased when there is no seat in a sports game, such as a baseball game, a basketball game or the like, and thus a visitor views a game while standing up, or when there is no seat during the use of a public transportation means, such as a bus, a train, a subway train, or the like.

In this case, in public places, such as an art gallery, a museum, and an ancient place, it is not easy to provide the places with chairs for rest due to the need to maintain an unobstructed circulation path for large crowds of visitors.

Meanwhile, since it is difficult for workers, such as a mart salesclerk, a hotel employee, a laundry worker, a beautician, an assembly line worker, a teacher, a parking assistant, a barista, a gas station worker, etc., who are working while standing up, to move to adjacent chairs, sit on the chairs, and take rest due to the characteristics of their work, problems arise in that blood circulation is not smooth and thus the degree of fatigue is high because they are working while standing up for a long time. Furthermore, they are exposed to pain in the waist, the legs or the feet or a cardiovascular disorder, such as a stroke, a cardiac infarction, a varicose vein or the like, in worst cases.

In order to overcome these conventional problems, there was a demand for the development of a chair that can be easily carried. Korean Unexamined Utility Model Publication No. 20-2012-000140 entitled “Combined Stick and Chair capable of Facilitating Carrying” and Korean Registered Utility Model No. 20-0336096 entitled “Portable Chair for Mobile Work” are disclosed.

A chair apparatus 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3 below.

FIG. 1 is a perspective view showing the configuration of the chair apparatus 1 according to the first embodiment of the present invention, and FIG. 2 is a sectional view showing the side sectional configuration of the chair apparatus 1.

As shown in these drawings, the chair apparatus 1 includes a pants unit 100 configured such that the body part of a wearer below his or her waist is inserted thereinto, and a chair unit 200 fixedly accommodated inside the pants unit 100 and configured to enable a user to sit.

The pants unit 100 is worn on the body part of the wearer below his or her waist. The pants unit 100 includes a buttocks reception part 110 configured to receive the buttocks H of the wearer, a legs reception part 120 configured to receive a pair of legs L, and a chair reception part 140 coupled to traverse the buttocks reception part 110 and the legs reception part 120 and configured to receive the chair unit 200.

The buttocks reception part 110 and the legs reception part 120 are formed by cutting out a pair of front and rear clothes in accordance with dimensions and sewing the clothes so that spaces for receiving the buttocks H and the legs L are formed therein. The chair reception part 140 is vertically coupled inside the buttocks reception part 110 and the legs reception part 120, and partitions the internal space of the pants unit 100 into the space into which the chair unit 200 is inserted and the space into which the body of the wearer is inserted.

The chair reception part 140 is formed by sewing a separate cloth on the inner wall surfaces of the buttocks reception part 110 and the legs reception part 120. The width of the chair reception part 140 is preferably a minimum width corresponding to the width of the buttocks support plate 210 of the chair unit 200 because the chair unit 200 can immediately react in the operation of the wearer.

In this case, the cloths that form the pants unit 100 are preferably made of flexible material in order to improve the wearing sensation of the wearer. Furthermore, when the cloths are made of flexible material, the distance between lower legs 230 and the legs L can be widened when the wearer sits, thereby improving a sitting sensation.

The chair unit 200 moves along with the wearer in the state of being accommodated inside the pants unit 100, and supports the wearer with respect to a ground surface so that the wearer can sit regardless of the location when the wearer desires to sit.

The chair unit 200 includes the buttocks support plate 210 configured such that the buttocks H of the wearer come into contact therewith and are supported thereby, upper legs 220 formed to extend downward from the buttocks support plate 210, the lower legs 230 formed to extend downward from the upper legs 220, first joints 240 provided between the buttocks support plate 210 and the upper legs 220, second joints 250 provided between the upper legs 220 and the lower legs 230, and ground surface supports 270 coupled to the lower legs 230 and configured to come into contact with a ground surface.

The buttocks support plate 210 is accommodated in the chair reception part 140 at a location corresponding to the buttocks H of the wearer. The buttocks H are seated on the buttocks support plate 210 when the wearer sits. The buttocks support plate 210 is preferably formed in a minimum size allowing sitting because interference can be minimized when the wearer is walking.

In this case, the buttocks support plate 210 is preferably formed in a gradually curved surface form, as shown in FIG. 2, by taking into account the curved shape of the buttocks H. The buttocks support plate 210 is rotated relative to the upper legs 220 around the first joint 240 s when the wearer walks or sits. Accordingly, the buttocks support plate 210 is maintained in a vertical state, as shown in FIG. 2, when the wearer stands up, and is rotated to a horizontal direction by a predetermined angle, as shown in FIG. 3, when the wearer sits.

The upper legs 220 and the lower legs 230 are disposed between the buttocks support plate 210 and the ground surface, and are operated in conjunction with the movement of the legs of the wearer. The upper legs 220 are disposed in accordance with the thighs, and the lower legs 230 are disposed in accordance with the calves. The upper legs 220 and the lower legs 230 are provided to be rotated relative to each other around the second joints 250.

The second joints 250 are formed at locations corresponding to the knees N of the wearer.

As to the upper legs 220, upper joint coupling portions 221 at the upper ends of the upper legs 220 are rotatably coupled to the buttocks support plate 210 by the first joints 240, and first inclined surfaces 223 that are coupled to the second joints 250 are provided at the lower ends of the upper legs 220. As to the lower legs 230, second inclined surfaces 231 at the upper ends of the lower legs 230 are coupled to the second joints 250, and the upper portions of the lower legs 230 are coupled to the ground surface supports 270.

In this case, each of the first inclined surfaces 223 and each of the second inclined surface 231 are inclined to form a predetermined angle θ therebetween. The first inclined surfaces 223 and the second inclined surfaces 231 are maintained in the state of being spaced apart from each other, as shown in FIG. 1, when the wearer stands up, and the upper legs 220 and the lower legs 230 come into contact with each other through rotation, as shown in FIG. 3, when the wearer sits.

When the wearer sits, the weight of the wearer is applied to contact surfaces between the first inclined surfaces 223 and the second inclined surfaces 231, and the center of gravity is formed by an angle at which the upper legs 220 and the lower legs 230 are inclined, thereby maintaining the state in which the wearer sits.

That is, when the wearer stands up in the state of wearing the chair apparatus 1, as shown in FIG. 1, the upper legs 220 and the lower legs 230 are disposed perpendicular to a ground surface. Furthermore, when the wearer walks, the upper legs 220 and the lower legs 230 operate to be bent around the first joints 240 and the second joints 250 in conjunction with the operation of the legs L because the chair unit 200 is in the state of being accommodated inside the chair reception part 140.

The first joints 240 and the second joints 250 are implemented in the form of shafts. The first joints 240 are coupled through the buttocks support plate 210 and the upper joint coupling portions 221, and the second joints 250 are coupled through the lower portions of the upper legs 220 and the upper joint coupling portions 221 of the lower legs 230.

The upper legs 220 perform link movement between the first joints 240 and the second joints 250, and may operate variously in accordance with the operation of the legs L. Furthermore, the lower legs 230 may operate variously in accordance with the operation of the legs L and the locations of the upper legs 220.

When the wearer sits, the upper legs 220 and the lower legs 230 are inclined such that the first inclined surfaces 223 and the second inclined surfaces 231 come into contact with each other, as shown in FIG. 3. In this case, the second joints 250 come into contact with the backs of the knees of the wearer. Accordingly, since the second joints 250 press the backs of the knees of the wearer and thus pain is caused, and cushion members 260 are provided in front of the second joints 250.

The cushion members 260 may be implemented as rubber or sponge having a predetermined thickness. Accordingly, when the wearer walks or sits, inconvenience can be reduced.

When the wearer bends the legs L to sit, the lower legs 230 are inclined at a predetermined angle with respect to a ground surface. The lower legs 230 are bent in a direction opposite the direction in which the feet F are directed. As the first inclined surfaces 223 and the second inclined surfaces 231 come into contact with each other, the weight of the wearer is distributed among the second joints 250, the ground surface supports 270 and the feet F. Furthermore, as the pair of ground surface supports 170 and the four points of the pair of feet F come into contact with a ground surface, the center of gravity is formed, and thus the state of sitting is maintained.

Meanwhile, in the chair unit 200 according to the above-described preferred embodiment of the present invention, the lengths of the upper legs 220 and the lower legs 230 are fixed. Accordingly, when the height of the wearer differs, there may occur cases where balance is not maintained when the wearer walks or sits.

As a result, as a chair unit according to another embodiment of the present invention, the length of each of the upper legs 220 and the lower legs 230 may be provided to be variable.

Meanwhile, FIG. 4 is a side view showing the configuration of a chair apparatus 1 a according to a second embodiment of the present invention. The chair apparatus 1 according to the previous preferred first embodiment is disposed in an integrated manner in the state in which the chair unit 200 has been accommodated inside the pants unit 100. In contrast, in the chair apparatus 1 a according to the second embodiment, a chair unit 200 b is coupled to the outside of a pants unit 100 a.

Although the configuration of the chair unit 200 b is the same, the chair unit 200 b is disposed on the back surface of the pants unit 100 a, and is coupled to the pants unit 100 a by fastening members 310. The fastening members 310 may be implemented as bands including male and female Velcro members.

The wearer may dispose the chair unit 200 b behind himself or herself in the state of wearing the pants unit 100, and may fasten the chair unit 200 b to himself or herself via the fastening members 310.

The chair apparatus 1 a according to the second embodiment of the present invention allows only the chair unit 200 b to be rented to a visitor in a place, such as a museum or an exhibition hall, and also allows the visitor to couple the chair unit 200 b to his or her pants and to sit at a desired location.

Meanwhile, FIG. 5 is a perspective view showing the configuration of a chair apparatus 1 b according to a third embodiment of the present invention.

In the chair apparatus 1 according to the above-described third embodiment of the present invention, the buttocks support plate 210 is implemented in the form of a single plate. In contrast, in the chair apparatus 1 b according to the third embodiment of the present invention, a buttocks support plate 210 a is implemented as a pair of support plates 211 and 213. Accordingly, the pair of support plates 211 and 213 are disposed on both side buttocks, and cause less interference while the wearer is walking than the buttocks support plate 210 of the chair apparatus 1 of the preferred embodiment, thereby increasing a wearing sensation.

In this case, a pair of support plates 211 and 213 are connected by a connection bar 215. In some cases, the length of the connection bar 215 is implemented to be variable, thereby further improving a wearing sensation.

As described above, in the chair apparatuses 1, 1 a and 1 b according to the present invention, the chair unit is coupled to the inside or outside of pants, and the wearer moves along with the worn pants in an integrated manner. In this case, the chair unit is accommodated inside the pants, and performs joint movement in conjunction with the operation of the legs of the first joint and the second joints, thereby causing minimum interference when the wearer walks.

Furthermore, in the chair apparatus, when the wearer desires to sit, the buttocks support plate stably supports the buttocks of the wearer, and the upper legs and the lower legs are bent and thus the center of gravity is formed, thereby enabling stable sitting.

Furthermore, in the chair apparatus, the chair unit is accommodated inside the pants unit, and thus the chair unit is not exposed to the outside, thereby providing the convenience in which the wearer can sit according to his or her desire anywhere and anytime without degrading aesthetic beauty.

A wearable chair apparatus 10 capable of facilitating storage and carrying according to a fourth embodiment of the present invention will be described with reference to FIGS. 6 to 16.

Referring to FIGS. 6 to 9, the chair apparatus 10 according to the present invention includes a buttocks fastening unit 400, a support unit 500, and a legs fastening unit 600.

The buttocks fastening unit 400 includes a body 410 and fastening strips 420.

In the body 410, a storage space is formed in the body 410, like in a common bag, and a zipper 416 is formed above an opening portion, so that a user can selectively open and close the body 410 by moving the grip 414 of the zipper 416. In the present embodiment, the body 410 is made of flexible material, and is formed in an elliptical shape having a predetermined length.

The fastening strips 420 are composed of a pair of strips, and are formed to extend from both side ends of the body 410, respectively. Velcro members 421 and 422 are provided on the fastening strips 420 as a fastening means. A user forms the pair of fastening strips 420 in the form of shoulder straps by fastening the Velcro members 421 and 422 formed on the pair of fastening strips 420, thereby enabling the body 410 to be carried on the shoulders in the form of a cross-bag, as shown in FIG. 15. When a user sits using the chair apparatus 10 of the present invention, the user surrounds the buttocks of the user with the body 410, surrounds the waist with the two fastening strips 420 and fastens the Velcro members 421 and 422 in a cross form, thereby fixedly wearing the body 410 on the buttocks of the user so that the body 410 comes into close contact with the buttocks of the user.

Meanwhile, in the buttocks fastening unit 400 of the present invention, the body 410 is provided with two pairs of auxiliary fastening strips 430, and buckle members 433 are formed on the ends of each pair of auxiliary fastening strips 430 as a fastening means. Accordingly, the user fastens the body 410 around the waist using the fastening strips 420. Additionally, the user may firmly fasten the body 410 to his or her buttocks by surrounding the thighs with the auxiliary fastening strips 430 and fastening the buckle members 433 at the ends of the auxiliary fastening strips 430.

Furthermore, the buttocks fastening unit 400 of the present invention includes fastening portions 440 so that the upper ends of the support unit 500 are detachably coupled to the body 410.

Referring to FIGS. 6, 10 and 11, each of the fastening portions 440 includes a socket member 442, a cover member 444, and fastening members 445 and 446.

The socket member 442 is fixedly mounted on the inner surface of the body 410. One side of the socket member 442 is open, and thus the fastening plate 530 of the support unit 500 may be inserted through the open portion. The socket member 442 is made of soft fabric material, such as leather, and may be coupled to the body 410 by sewing. However, the socket member 442 is not limited thereto. The socket member 442 may be made of hard plastic material, and may be bonded to the body 410. Any configuration may be employed as long as the fastening plates 530 can be inserted and thus the fastening plates 530 can be coupled to the body 410.

The cover members 444 are formed to extend from the opening portions of the socket members 442, and are configured to cover the opening portions of the socket members 442 in the state in which the fastening plates 530 have been inserted into the socket members 442.

The fastening members 445 and 446 are composed of Velcro members, and are formed on the socket member 442 and the cover member 444. Accordingly, the fastening members 445 and 446 fasten the cover members 444 to the socket members 442, thereby preventing the fastening plates 530 inserted into the socket members 442 from being separated therefrom.

In this case, any configuration in which two members are detachably fastened to each other, such as dot buttons (snap buttons) or general buttons, other than Velcro members, may be applied to the fastening members 445 and 446.

The support unit 500 is configured such that the upper end thereof is detachably fastened to the body 410 of the buttocks fastening unit 400, and supports the body 410 against a ground surface so that the user can sit.

The support unit 500 includes rod-shaped lower legs 510 configured to have a predetermined length, upper legs 520 formed to extend above the rod-shaped lower legs 510, the fastening plates 530 formed to extend above the upper legs 520, first joints 540 provided between the lower legs 510 and the upper legs 520, and second joints 550 provided between the upper legs 520 and the fastening plates 530.

When the lower legs 510 and the upper legs 520 are worn by a wearer, they are disposed between the fastening plates 530 and a ground surface, and operate in conjunction with the movement of the legs of the wearer. The lower legs 510 are disposed in accordance with the calves, and the upper legs 520 are disposed in accordance with the thighs.
